To all whom t may con/cerne Be it known that I, 4WILLIS LINcOLN MARSH a citizen of the United States, resid ment or similar material to various articles,

the machine being adapted especially for the application of rubber or other cement` to the sections of a shoe-up er prior tostitching.- i

A further object o the invention is to pro-v vide e machine in which the cement4 may bev s arranged in a closed vessel or reservoirin order, to avoid loss b evaporation Aand in which it is dischar e beii-lpassed throug the machine.

cement is fed from a reservoir by an apply-y ing-roller that is operated through the Incdium of the strips of leather-or other articles 2 5 to which the cement isbeing applied.

With these and other objectslin view, as'

Will more' fully hereinafter appoarfthe iiiveni tion consists iii certain nove eatures Ofcom struction and arrangement of parts, here 3c inater fully described,v illustrated in the accompanying drawings, and Iparticularly pointe out in the a pended claims, it being understood that various changes in the form, proportions, size, and minor details of the' structure may be made without departing from the s irit or sacrificing any of the advanta eso theinvcntion.

In t e accompanying drawings, Figure 1 is a vertical section of a cementin -macliine 4o constructed in'accordance with t e invention. Fig. 2 is a transverse sectional view of the same on the line 2 2 of Fig. 1. Fig. 3 is a sectional plan view on the line 3 3 of Fig. 1. Fig. 4 is a detail sectional view illustrating a sli ht modification of the invention.

imilar characters of reference are employed to indicate corresponding (parte throughout the several figures of the rawin l ,i glhe working parts of the machine are sup-I Ing at gt. Louis, in the State ofMissouri, have` only while goods .arev

' Y.plates are provided with bearings for the re rther object of the invention is to pro" caption of a short shaft or stud 21 on which vide a cement-applying machine in which the .1

v-iieripheryof which is prefere the shaft is arranged a belt-wheel 13, which of Ower. j l

f t the head of the machine is arranged a pair of parallel horizontal plates 14, forming supports for a'pair of spaced vertical guide- Vmay receive motion from any suitable source bars 15, that extend through 1u s 16, formed at the rear ofl a'vertically-i'riova le reservoirsupporting plate 17. This plate 17 carries a vreservoir 18 which may be of any desired size, and when used to contain rubber or similar cement is preferably rovided with a cover 19 in order to prevent oss by evaporation. l

I The plate 17 forms the rear Wall of a discharge-neck leading from the bottom of the reservoir, the front wall of said neck being formed by a plate 20. These two walls or is mounted acenient-applyin roller 22rthe ly corrugated in order that in rotating it may positively feed'the cement from the reservoir. The two plates 17 and 20 are arranged to iit very closeij/` against the opposite sides of the roller 22 and prevent the escape of an cement by leakage. The opposite end wa ls 24 of the d isch argeneck are sligh tl)r curved at the bot tomiin order to follow the contour of the louer portionl of the roller, alpd tfliese eid wa s carry'p ate-sp 25,t at t snug y against the periphery oi the roll and serve as doctors toprevent the passage of any cement except the thin film which will cling to the periphery ofthe roller and the cement which will remain in the grooves formed in the periphery of said roller.

The a plying-roller 22 is arran ed directly above t e work-supporting rol er l2, and when a strip of leat er or other material to which the cement is to be applied is placed between the rollers the strip will serve as a.

Ameans fortransmitting movement from the a lever 27, Vthat is pivoted on a stud 28, carried by the frame, and the roar end of such lever is connected to the frame b a tensionspring 29, which normali will ho d the reset# voir and the ap lying-ro ler elevated, so that er, the latter being held 1 los the applyin -ro ler will b`e held from engalement with t e work-supporting roller.

2 ssase front end of the lever 27 is connected by a rod 3() to a pedal 31 within convenient reachA of the operator, and when the pedal is depressed the front end of the lever is pulled.

In Fig. 4 is il ustrated a slight modification of the invention, wherein the feed-roller `l2 remains in place, While the' reservoir 18 is provided with a discharge-neck 20 of somewhat modified construction, and from the neck leads a tube 30, through which the cement or other adhesive may be supplied'to a brush 3l, arranged to rest on the mategial Atthe rear of the brush a roller or disk 33 may be placed for the purpose of maintaining the material in proper position and to assist infeeding movement. The auxiliary neck 20', the brush, 'and the disk 33 may be ead, ily substituted for theneck 20 and' cementfeeding roller shown in Figs. 1 and 2, as occasion requires.

1. In a machine of the class described, the combination with a work-su porting roller, of means for revolving the ro ler, a normally inactive cement-applying roller, and a cement-reservoir from which cement is fed hy the a plying-roller, the latter receiving motion t ough the material placed on the worksupporting roller, and to which the cement is to be applied.

2. In combination, a work supporting roller, a vertically-movable cement-reservoir, a cement-applying roller projecting from the bottom of the reservoir, and adapted to engage the material resting 'on the work-sulpportingroller, and means for revolving t e work-supporting roller, thereby to transmit movement to the cement-applying rollerl through the intervention of the material between said rolls.

3. In a machine of the class described, the

combination with a yieldable work,-support.

ing roller, of a shaft carrying the same, means for revolving the shaft, a vertically-guided cement-reservoir having a contracted discharge-neck at its lower end, a cement-appl ing roller projecting from the bottom of t e neck, a spring tendln to raise the reservoir,`

and maintain the rol ers out of contact, and means for overcoming the stress of the spring to permit movement of the reservoir and cement-applying roller in the direction of the work-supporting roller.

` 4. In a machine of the class described, the combination with a frame, of a shaft journaled therein, a yieldable work-supporting roller mounted on said shaft, a' pair of vertically-disposed s aced bars carried by the frame, a vertical -m'ovable plate having perforated lugs through which said bars extend, said plate forming the rearwall of the discharge-neck, a reservoir communicating with r such dischar e-neck, yfront and rear plates arranged to orm'the remaining walls of the discharge-neck, a shaft journaled in the front and rear lates, a cement-applyin roilercarried by t 'e shaft, doctors carried )y the end walls of the neck a'nd engaging the periphery of the roller, a spring-actuated lever nor- 'mally tending tol elevate the reservoir, and

roller, and a pedal connected to said lever for overcoming the stress of the s ring.

In testimonyl that I claim t e foregoing as my own I'have hereto aiixed my signature in the presenceof two witnesses.
